be concerned with spatial correlation, at any rate.
A 'conventional' way would be the regression analysis
between the two variables mesh by mesh, lattice by lattice,
polygon by polygon...
There seems to be 'semi-variogram', 'kriging'...but I have no
sufficient knowledge to talk about it.
(I would appreciate comment from geostatisticians on
In this case, you have to bear in your mind that
'the degree of correlation between the variables
is a function of the size of area considered'.
'Any talk of single correlation coefficient between variables
measured on modifiable units is erronious'
